Depending from the needlecylinder is the take-upfor the knitted fabric, of which only part of the arms c are shown. Thearm 0' carries a cam adapted to actuate byintermediate mechanism thedriving mechanism for the pattern-chain. Supported upon opposite sidesof the bed-plate are two posts 6 e, which carry the crosstreef, fromwhich are hung the dial-cap, dial, and connected parts. The parts so fardescribed are or may be all as is common in this class of machines.

Rigidlysupported in the centerof the crosstree and depending verticallytherefrom is the dial-shaft g, which is adjustable vertically in theusual manner to vary the length of the stitches bythe hand-nut h andheldin its adjusted position by the set-screw 2'. Upon the dial-shaft issecured the dial-cap 7.: by means of a set-screw which passes throughthe hub Zof the dial-cap. Rotatably mounted upon the dial-shaft belowthe dial-cap is the dial 1 m, which is slotted radially in its outerupper portion for the reception of the dial-needles. The dial issupported by means of a collar 12, fastened by a set-screw to thedial-shaft and rotated by the needle-cylinder by means of theusualdriving-lugs projectinginward from the inner surface of theneedle-cylinder,which engage the lugs o, pivotally supported upon thelower side of the dial.

Upon the lower surface of the dial-cap are mounted eight sets ofknitting-cams. The number, however, is entirely immaterial, except thatthere must be an even number, and there must be the same number in thecamcylinder. Of these four sets are fixed and alternately with them fourhave loose throwingout cams. In case there were some other number ofsets of knitting-cams then alternate throwing-out cams would be loose.By reference to Fig. 4 it will be seen that there are provided int-heform illustrated four fixed throwing-out cams It and four loosethrowing-out cams 10 The remaining cams are fixed, k designating thethrust-cams, k the draft-cams, and k the guard-cams, the oflice of thelast-named being simply to prevent the needles from jumping on suddencontact with the thrust-cams during fast running of the machine. Thethread-guides are designated k and lead the thread to both the cylinderand the dial needles at the same time.

During the knitting of the tube of tuckrib the loose throwing-outcamswill be held in their inner or retracted positions by the springs 75,attached to pins 10 carried by straps Z69 and movable in radial slots 10cut in the dial-cap inside of the cams, the straps passing under a ringis and being pivoted at their outer ends to the upper sides,respectively, of the loose throwing-out cams. In

other words, the loose throwing-out cams are normally held in theirretracted positions, so that When'a needle is moved out by the ad-'jacentthrust-cam it will take thread, but not of the tube.

the needle, and as the next throwing-out cam is fixed in the outerposition the needle will be forced farther out than before and so thatboth threads will pass behind the latch and, on the needles being drawnin, be cast ofion the thread just taken in the hook.

Opposite the pin it and supported on the strap 10 before referred to, isa cam-pin I0 adapted to be engaged by the cam-disk 10 by means of whichat predetermined inter vals the loose throwing-out cams are moved totheir outer positions, so that plain rib will be knit around a portionof the circumference If all the throwing-out cams were held out to thesame position as that 0ccupied by the fixed throwing-out cams, theneedles would all be moved out, so that the loops would all pass behindthe latches at every successive reciprocation of the needlesand plainstitches made by all of the needles.

The cam-disk and associated parts'and the mechanism for moving it willnow be described. This cam-disk consists of a disk mounted in thedial-cap and provided in its center with a slot The size of the disk issuch that when it is in its central position it will not engage any ofthe cam-pins Z0 In this position the dial-shaft will occupy the centerof the slot. Upon the upper side of the dial-cap is a yoke 10", which isconnected by a strapp with a bell-crank arm 19, pivoted at one sideofthe machine and carrying upon its outer end a bowl adapted to be engagedby the pattern-chain d, before referred to. This pattern-chain d haslinks of three heights, the low links being lettered cl and themedium-height links being lettered d and the high links being lettered dWhen the low links are passing under the bowl ofthe bell-crank arm, theyoke I0 will be shifted to the left of the position shown in Fig. 23,and when the medium-height links are under the bowl of the bell-cranklever the yoke will be shifted to its middle position, as shown in Fig.2, and when the high links are under the bowl the yoke will beshifted-to the right of the position shown in Fig. 2. This yoke carriesa shifting-pin 7e which projects downwardly through the dial-cap into aposition to engage two cam-levers pivoted upon the upper side of thecam-disk. "The outer of these two cam-levers, k", is pivoted at one endand held in its normal position, shown in Fig.5, by a spring connectedto its extreme end. The inner cam-lever I0 is pivoted upon the pin 10and heldin its normal position, as shown in Fig. 5, by aspringconnectedto one of its ends. When the yoke is moved to the leftof the positionshown in Fig. 2, it will move the shifting-pin 7.3 outwardly, and thepin, engaging the cam-lever is upon the camdisk, will movethe disk tothe left of the position shown in Fig. This motion of the cam-disk isnormally prevented by the stationary looking-pin m, fixed in andprojecting upwardly from the dial,and which engages one of three notchesin the cam-lever it; but when r the cam-lever it" is moved outwardly itcarries a connectingslide k This slide is placed in a recess in theunder side of the cam-disk and carries at its two ends pins 7t' and 76The pin 7t projects upwardly through a slot in the cam-disk and engagesa slotin the cam-lever it", so that when the cam-lever it is movedoutwardly it moves the connectingslide outwardly. The pin 70 upon theother end of the slide projects upwardly through an inclined slot 76 inthe cam-disk, and as the slide is moved outwardly the pin is forced bythe inclination of the slot away from the center of the disk and in suchdirection as to cause it to engage and rock the cam-lever it, to therebyrelease the cam-lever from engagement with the locking-pin m, whereby onthe further rotational movement of the camdisk against the shifting-pink the cam-disk will be permitted to move and be moved to the left of theposition shownin Fig. 5. This slide is in effect a connection betweenthe two levers It" and 70 so that the operation of the lever 70 willcause the releasing of the lever 7o from engagement with the pin m.IVhen the yoke is moved to the right of the position shown in Fig. 2,the shifting-pin it will be moved toward the center of the dial andengage the cam-lever h The first result of this contact is to oscillatethe cam-lever]; and to release it from engagement with the locking-pinm, unlocking and permitting the further rotational movement of thecam-disk against the shifting-pin k to move the camdisk to the left ofthe position shown in Fig. 5. The radius of curvature of thecam-pinengaging portions of the cam-disk is such that when it is in itsextreme right or left position it will engage the cam-pins [e on theinclined surfaces 76*, force them outwardly, and during the sweeping ofthe surfaces W past the cam-pins it will hold them stationary and at thesame distance from the center until shoulders 79 are reached and thepins are permitted to be retracted by their springs. The three notchesin the lever It serve to hold the cam disk in its three positions,namelyt he right, the left, or the middle position. Vhen the cam-disk ismoved to the left, it results in the formation of a block of plain ribupon the side of the tuck-rib tube toward which the cam-disk is moved,and when the cam-disk is moved in the opposite direction it results inthe knitfing of a block of plain rib in the opposite side of the tuckribtube, and when it is in its middle position it is inactive and allowsall of the loose throwing-out cams to be held by their springs in theirinner positions so that the tube will be formed of tuck-rib stitch. Itwill be seen that the pin k projecting upwardly from the surface of thecam-disk will prevent more than a certain amount of oscillation of thecam-lever 7t. When the cam-lever shall have been moved by its engagementwith the shifting-pin or by the engagement of the cam-lever 7.; with theshifting-pin indirectly through the slide so that the pin m isdisengaged from the notch which it occupied therein, any furthermovement of the camlever or either'of them against the shiftingpin kwill result in sliding the cam-disk to the right or to the left, as thecase may be. This cam-disk is held from rotation with relation to thedial by a guide-pin m fixed in the dial and projecting upwardly toengage the radial guide-slot 70 cut in the cam-disk. Thus the two slotsIt and W, the one occupied by the dial-shaft and the other by theguide-pin m completely constrain the movements of the cam-disk toright-line movements in the direction of the slots. So it is seen thatthe cam-disk rotates constantly with the dial, and the result is, asbefore indicated, that each cam-pin I0 is moved out in turn as thedialand cam-disk revolve; but to whichever side of the dial the camdiskis shifted the group of needles on that side will knit plain stitch asthe cam-disk comes in contact with the cam-pin 76 and the remainder ofthe tube will be tuck-stitch. It must of course be understood that asthe dial and its needles and the cylinder and its needles are bothrevolving in the same direction and at the same rate of speed the fabricis carried with them and that the cam-disk preserves a constantrelation, so far as rotation is concerned, to the fabric.

Throughout the specification and claims I have used the expressionplainstitch to distinguish from tuck-stitch, both of which indicate thecharacter of the stitch, whether the fabric be ribbed or plain. I havealso used the expression set of needles to designate the needles all ofwhich are operated upon by one series of cams-as, for instance, thedial-needles constitute one set of needles and the cylinder-needlesconstitute another set of needles; but I do not specifically limitmyself to such arrangement of the needles, for both sets of needlesmight be supported on dials or on cylinders or on cones, as desired. Bythe expression group of needles I have designated those needles of a setof needles which operatein a different manner from the remainder of theneedles of the setas, for exam ple,the dial-needles which knit the blockof plain stitch in the tube of tuck-stitch constitute a group ofneedles. By the expression similar needles, wherever I have used thosewords in the claims, I desire to limit the combination to one in whichthe needles are all alike,to sharply distinguish from machines whichemploy needles some of which have their heels in one place on the shankand some in a different position, adapting them for ac tuation bydifferent sets of actuating-cams, or which employ needles differing fromeach other in other respects.

My invention is applicable to the cylinderneedles as well as thedial-needles by making such changes as are necessitated by the change oflocation. I do not, therefore, limit my claims to the precise form ofmachine described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
